A drive aggregate may include an electric motor, a motor control for activating the electric motor, a housing, and a circuit board holder. The electric motor may include a rotor rotatable around an axis of rotation. The motor control may include a circuit board with a power electronics. The housing may include a base body receiving the electric motor and a cover receiving the motor control. The circuit board holder may support the circuit board and may be arranged axially between the base body and the cover. The base body and the cover may be composed of a metal. The circuit board holder may be composed of a plastic.

Drive aggregate

An electric battery may include a battery housing, a plurality of battery cell modules, an electrical current conduction, and a cover. The battery housing may include a plurality of housing cut-outs that are sealed via a cooling plate. The battery cell modules may be configured to store electric energy and may be thermally connected to the cooling plate. Each of the battery cell modules may include an electrical positive connection and an electrical negative connection. The electrical current conduction may be configured to supply the battery cell modules electric energy. The electrical current conduction may include a first electrical conductor rail and a second electrical conductor rail. The cover may be detachably coupled to the battery housing. The first conductor rail may include a plurality of rail elements. One of the rail elements may be configured to electrically connect adjacent battery cell modules.

Electric battery and motor vehicle

A side channel compressor for compressing gas includes a housing, which forms a side channel, and an impeller drive arranged in the housing. The housing forms a feed channel fluidically connected to the side channel for feeding gas to the side channel and a discharge channel for discharging gas out of the side channel that is fluidically connected to the side channel. The feed channel branches into two separate channel arms each extending along a channel arm center axis. The housing is subdivided along a separating plane into first and second housing parts which sealingly lie against one another. The discharge channel is passed through between the two channel arms and either a first or second discharge channel part of the discharge channel, opens out on a connecting surface of the first or second housing part forming a gas outlet opening arranged apart from the separating plane.

Side channel compressor for compressing gas

A housing part for a multi-part housing of a battery unit may include a bottom portion and a side wall structure arranged circumferentially on the outside along the bottom portion in the circumferential direction. The side wall structure may form at least one side wall portion along the circumferential direction. The side wall portion may have an inner wall facing the bottom portion and an outer wall, which may be spaced apart from the inner wall and may face away from the bottom portion. The inner wall may be connected to the bottom portion. The inner and outer walls may be connected to one another via a framework-like cavity structure having several webs, which may be adjacent to one another in the circumferential direction and which, in the cavity structure, may form several cavities adjacent in the circumferential direction and connecting the inner wall to the outer wall.

Battery housing part

An internal combustion engine for a motor vehicle includes a crankcase ventilation device for removing blow-by gas from a crankcase, a pressure sensor being provided for measuring the gas pressure in said crankcase, and a control unit connected to and in communication with the crankcase ventilation device being configured and/or programmed to run a tightness test for said crankcase ventilation device when the internal combustion engine is switched off.

Internal combustion engine for a motor vehicle

A clutch apparatus may include a first shaft member having a first end portion including axially extending first protrusions. The clutch apparatus may also include a second shaft member arranged axially opposite the first shaft member, the second shaft member having a second end portion including axially extending second protrusions. Additionally, the clutch apparatus may include a clutch member having a disk-shaped main body arranged between the first shaft member and the second shaft member, the clutch member including an annular rim that encircles the main body and protrudes beyond the the main body in both axial directions, the annular rim including first recesses disposed on a first side of the clutch member and second recesses disposed on a second side of the clutch member. The second end portion may further include at least one latching element and the clutch member may further include at least one mating latching element.
